The plugin and the app are wonderful if you're writing fiction and want to be accurate. I can find the locations I'm using and explore them almost as thoroughly as if I were there in person. Thanks, Google. :)

5.2.1.1547 (and not 5.2.1.1329) is the latest version for Mac OS X 10.6.x (Snow Leopard). AppFresh reports 5.2. This info is probably ( read from Contents/Info.plist, where CFBundleShortVersionString = 5.2 but CFBundleGetInfoString = 5.2.1.1547.
Is that a bug of AppFresh?

"I just read in a German online magazine that Google Earth contains a "hidden" yet complete flight simulator! Currently, two jets are available (F16 and SR22), and also the list of airports is not that long. Just open Google Earth (you'll need the newest version, 4.2), and then type Command-Option-A."
